There is provided a scaffold for bone regeneration which is adapted to be implanted at a bone defect site of a bone. The scaffold comprises a main support member configured to be fixed to the bone, and a load supporting unit configured to be installed in the bone defect site of the bone to selectively bear a load applied to the bone. The load supporting unit includes one or two supporting pieces to be installed in the bone defect site of the bone to selectively bear a load applied to the bone. The supporting piece has at one end portion a contact portion to be brought into contact with and fixed to a compact bone in the bone defect site of the bone. The other end portion of the supporting piece is selectively coupled to the main support member.
